Need the updated parameters for push_transaction

Question

I have some problems trying to transfer EOS in push_transaction. I followed the instructions from https://steemit.com/eos/@noprom/using-eos-rpc-api-to-transfer-eos and other references because the documentation was outdated.

Here is the detail for my push_transaction :

http://127.0.0.1:8888/v1/chain/push_transaction

{  
   "compression":"none",
   "signatures":[  
      "SIG_K1_Ki1Q8SAiZnBWhjkMQM5gmaBhigGrFdVvgrKfpSue75NbR6Er2hinxWapbbE94YCnyPRcqUZizjjFao1oNyHGJUYFR4MeEF"
   ],
   "transaction":{  
      "actions":{  
         "account":"idxtester121",
         "name":"transfer",
         "authorization":{  
            "actor":"idxtester121",
            "permission":"active"
         },
         "data":"1044b82a63957b729015d266a9c8a67ef04902000000000004454f5300000000087465737473656e64"
      },
      "delay_sec":0,
      "expiration":"2019-01-16T07:31:47",
      "max_kcpu_usage":0,
      "max_net_usage_words":0,
      "ref_block_num":21690,
      "ref_block_prefix":2522481250,
      "region":0
   }
}

Below is the response :

object(stdClass)#31 (3) {
  ["code"]=>
  int(500)
  ["message"]=>
  string(22) "Internal Service Error"
  ["error"]=>
  object(stdClass)#32 (4) {

        ["file"]=>
        string(11) "variant.cpp"
        ["line_number"]=>
        int(545)
        ["method"]=>
        string(9) "get_array"
      }
      [2]=>
      object(stdClass)#35 (4) {

        string(29) "Failed to deserialize variant"
        ["file"]=>
        string(18) "abi_serializer.hpp"

        ["method"]=>
        string(12) "from_variant"
      }
    }
  }
}

From the error response, I think I missed some parameters. What are the updated parameters for push_transaction?

Answer 1

I think the data format is incorrect to unserialize.

You can use cleos --return-packed or -j to get the packed or jason result.

eg:

$ cleos -u http://jungle2.cryptolions.io:80 transfer -d -j eostemptest1 eostest11111 "1.0 EOS"
